Well... where to say... yeah, what I keep are two small poodles and both of them are boys. You know, the poodles are very active let alone that they are at a young age, 2 months. For me, it is a bit hard to set up a traditional fence because of some reasons... So I decided to try the wireless containment system to help me keep them in a safe area. I believe no one would wanna lost their pets no matter what they are. Lucky it is the first product purchased and it is pretty good such as the friendly customer service the fast delivery, and the best point is good enough to tie on their necks. I have worried that it might too big for my small dog because on the instruction it says no less than 10 pounds, which is near their weight. But after I but them, I found it was out of the question.
